High‐resolution nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique for obtaining chemical structure information. Its quantitative and noninvasive properties have led to its growing popularity as an analytical tool in many fields, including biology, chemistry, medicine, and food science. During transportation and storage, chemical reactions among the many nutrients lead to a loss of food quality. In these circumstances, portable NMR spectrometers can readily be used for food inspection and quality control. Because of the heterogeneous tissue distribution in food, a high‐resolution NMR method is required for detailed food inspection. Therefore, in this study, we demonstrated the feasibility of using an intermolecular double‐quantum coherence signal to obtain high‐resolution metabolic profiles of several fruits, including grape, cantaloupe, tomato, and watermelon. The resulting high‐resolution NMR spectra facilitate the identification of important metabolites, which can be used as biomarkers for food quality control. The method established here may be adapted for food inspection using portable NMR equipment.

使用核磁共振波谱法快速检查水果

高分辨率核磁共振波谱学是获取化学结构信息必不可少的技术。它的定量和非侵入性特性使其成为许多领域的分析工具,包括生物学,化学,医学和食品科学。在运输和存储过程中,许多营养素之间的化学反应会导致食品质量下降。在这种情况下,便携式NMR光谱仪可轻松用于食品检查和质量控制。由于食品中组织的分布不均,需要使用高分辨率的NMR方法进行详细的食品检查。因此,在这项研究中,我们证明了使用分子间双量子相干信号获得几种水果的高分辨率代谢谱的可行性,包括葡萄,哈密瓜,番茄和西瓜。由此产生的高分辨率NMR光谱有助于鉴定重要的代谢产物,可将其用作食品质量控制的生物标记。此处建立的方法可适用于使用便携式NMR设备的食品检查。
